Yield And Quality

During the processing of frozen and thawed sugar beets, invert sugar, in particular glucose and fructose, accumulates in them. This is due to the process of hydrolysis of carbohydrates. As a result of temperature fluctuations, beets lose elasticity, and tissue walls become soft. The activity of microorganisms intensifies on damaged beets. In the sugar industry, harmful microorganisms enter the production with raw materials, water, unwashed soil and air. Under improper storage conditions of raw materials the rapid development of microorganisms begins leading to sugar loss. The microflora of raw materials in sugar production is due to spore-forming and non-spore-forming bacteria, as well as micromycetes. Processing in the production of such raw materials is complicated. This leads to non-rhythmic operation of the sugar factory, technological processes and metal corrosion of technological equipment. Sugar yield and quality are significantly reduced. An important factor is the protection from the formation of microbial biofilms. The article considers the problem of formation of microbial biofilm in the process of obtaining diffusion juice in the sugar industry. The structure of the biofilm and its stability over time are considered. Under the conditions of active biofilm formation, uncontrolled unaccounted losses of sucrose are observed. Under conditions of low-quality beet processing, biocides and enzymes must be used in the production. They reduce the contamination of intermediate products by microorganisms, greatly facilitate the technological process. They also allow you to predict unaccounted sugar losses and improve its quality and yield. The article considers the effect of different types of biocides on dextran, which is an example of the formation of microbial biofilms. The comparative characteristic of influence of biocides on dextran is given and their resistance is noted.

Optimal Quality

Sugar industry is one of the vital sectors in improving the economy of any country. But, sugar industries are striving hard to increase their profitability due to high cost of sugar production accompanied with low selling price. Without resorting to radical restructuring of sugar plant, but through proper planning, annual savings can be improved. One of the artifices to address this issue is through improving the quality of sugar so that selling price can be increased which in turn generates more revenue to the plant. The Juice Sulphitation process, as applied in the manufacturing of sugar, is a subject of such wide-spread interest. The mixed juice from the mills contains soluble and non-soluble suspended non-sugars. These impurities are to be precipitated by the judicious and controlled addition of Milk of Lime (CaO) and subsequent neutralization by Sulphur Dioxide (SO2) gas. This paper attempts to improve the quality of sugar by optimizing the quantity of lime (in the form of milk of lime) and sulphur (in the form of SO2 gas) added in the juice sulphitation process of a sugar plant. Two factor factorial experimentation was adopted to obtain an optimal combination of lime and sulphur quantities. Data of Transmittancy test on sugar juice was collected by varying the quantities of lime and sulphur. Analysis of Variance (ANOVA) table was plotted which explored the significant effects of individual treatments and interaction effects. Further to this, comparison of treatment means was carried out to find out the best treatment combination values for achieving the optimal quality of sugar from sugarcane.

Quality Of Products

At present time a lot of methods are used for the assessment of product quality level, as well as its manufacturing perspectives. Only quantitative data can be used in order to compare the competitiveness of products, facilities, companies, etc. But methods for quantitative assessment of technological processes competitiveness have not been still proposed. The present paper describes a developed procedure for evaluation the competitiveness of technological processes. It takes into consideration the main factors which are used for estimation of process effectiveness: quality of products, level of applied technologies and production costs. In order to range these parameters, it is proposed to use weighting factors for each of them. An integrated efficiency index may vary within a range of 0 to 1. This method allows not only evaluating competitiveness of production processes, but also choosing the most rational production process, based on required properties of the processed item. The application of the developed approach is shown on the example of reinforcing steel manufacturing, which can be produced in different ways. The obtained results of calculation present a comparison of selected manufacturing techniques by the following parameters: strength and ductility properties of reinforcing bars, an applied forming method, possibility of a layer winding and a range of diameters of bars in coils. It is shown that the developed model makes it possible to determine a trend in development or adjustment of operating parameters for existing options of processes applied at an operating plant.

The article discusses garments, underwear for children, made from knitted fabrics. One of the reasons for the low demand for Russia-made garments is incomplete satisfaction of consumer requirements for their quality. The analysis of defects arising at all stages of the technological process of manufacturing a product is carried out. It was found that the main group is made up of defects in the sewing and preparatory sections (about 80 % of the total number of reasons for the decrease in the quality of products). At the same time, the largest share is made up of defects arising in the sewing area (42.1 %). The efforts of the engineering and technical personnel of the enterprise should first of all be directed to eliminate these defects. For a targeted search for the causes of defects in the process of manufacturing garments, additional factors were identified that were systematized and recommended for use.
